渭河下游河道横断面调整特点及原因简析
Actually correction coefficient of kinetic energy reflects the non - uniform characteristics of cross - sectional velocity in natural rivers . it is related with hydraulic parameters and can be expressed by chezy ' s coefficient . the larger the resistance of boundary , the more non - uniform the distribution of cross - sectional velocity
动能修正系数实际上反映了河道横断面流速分布的不均匀性，与断面的水力要素有关，可用谢才系数c来表示，水流所受的阻力越大，边界对其影响也就越大，流速分布愈不均匀，导致动能修正系数增大。
